Which country entirely surrounds Vatican City?

The country that entirely surrounds Vatican City is Italy.

Vatican City is a sovereign, landlocked city-state situated within Rome, the capital of Italy. It is an enclave: every portion of its land boundary meets Italian territory. The border includes walled sections, streets, buildings, and the edge of St. Peter's Square.

The modern state was established by the Lateran Treaty, signed in 1929 between the Holy See and the Kingdom of Italy. The agreement ended the long-running Roman Question and recognized Vatican City as the territorial base of the Holy See's independence.

Vatican City is distinct from the Holy See, although the two are closely connected. The Holy See is the Catholic Church's central governing authority and diplomatic entity, while Vatican City is the sovereign territory that supports its independence. Switzerland, Austria, and France do not border Vatican City.
